Have a look at the ggplot2 package. You will find a lot of examples at
http://had.co.nz/ggplot2/
library(ggplot2)
dataset <- data.frame(x = seq(-1, 1, length = 101))
dataset$y <- dataset$x + dataset$x^2
dataset$z <- 10 * dataset$x + 1
ggplot(dataset, aes(x = x, y = y, colour = z)) + geom_point()
ggplot(dataset, aes(x = x, y = y, colour = z)) + geom_line()
ggplot(dataset, aes(x = x, y = y, colour = z)) + geom_line(size = 2) +
scale_colour_gradient2(low = "blue", mid = "yellow", high =
"red", breaks = seq(-9, 11, by = 1))

To call in the statistician after the experiment is done may be no more than
asking him to perform a post-mortem examination: he may be able to say what the
experiment died of.

The combination of some data and an aching desire for an answer does not ensure
that a reasonable answer can be extracted from a given body of data.

Onderwerp: [R] 2d color coded line plot
Hi! I'm not experienced very experienced with R and i'm looking for a
way doing plots like in this example
http://www.mathworks.de/matlabcentral/fx_files/23566/2/color_line3.png,
which basically it is a 2d plot in which the 3rd dimension (variable) is color
coded. I have only seen elsewhere that it is possible to color code dots in a
scatter plot and I tried it with success although I I didn't find a way of
including the color bar has legend to the plot.
I wonder if any one can give me some hint on this.
Thank you!
Gon?alo
